“…These cases characterize what is implied by the third and fourth principles of genealogical concordance, concordance in the geography of gene‐tree partitions across multiple codistributed taxa implicates shared historical biogeographic factors in shaping genealogies (Avise & Ball, 1990). This fact corresponds to the geological history of the Ponto–Caspian region, as the historical Black and Caspian Sea basins have been intermittently separated and connected over the past 5 Ma associated with Pliocene and Pleistocene glaciations (Reid & Orlova, 2002), promoting isolation, adaptation and divergence into localized, distinct lineages in many taxonomic groups (Dumont, 1998, 2000; Naseka & Bogutskaya, 2009).…”

“…Syngnathus abaster was originally described from Nice, France (Fricke, Eschmeyer, & Van derLaan, 2020). However, Naseka and Bogutskaya (2009) without examining any genetic materials and fish samples elevated S. n. caspius to species level ( S. caspius ) mainly based on the argument provided in Tarasov (2001) which was derived from previously published data on differences in morphology, ecology, and parasitic fauna of the Caspian and the Black Sea Atherina , Syngnathus, and Knipowitschia species. Later, this taxonomic recognition was adopted by Esmaeili et al.…”

Genealogical concordance, comparative species delimitation, and the specific status of the Caspian pipefish Syngnathus caspius (Teleostei: Syngnathidae)

To evaluate the specific validity of the Caspian pipefish Syngnathus caspius, we used a comparative molecular species delimitation method on a COI barcode library of Syngnathus, as well as principles of genealogical concordance. Comparative species delimitation allowed us to delineate putative species without a priori assignment of individuals to nominal species, while genealogical concordance extended our species delimitation results to multiple genes, multiple codistributed species, and comparisons with biogeographic evidence. All species delimitation analyses including two topology‐based, one network‐based, and one distance‐based analysis showed genetically isolated lineages of pipefish in the Black and Caspian Sea, corresponding to S. abaster and S. caspius, respectively. Mean evolutionary divergence between the two lineages (0.029) was within the range separating species of Syngnathus (0.024–0.217). The interclade/intraclade ratio of variation was comparable to the operational criterion of divergence between clades greater or equal to 10 × the level within clades to recognize separate species. Our argument on taxonomic validity of S. caspius is also supported by the principles of genealogical concordance as a conceptual basis for recognition of biological species. As a second objective, using a limited number of S. caspius specimens from two semi‐confined water bodies along the Caspian Sea south coastal zone (i.e., Anzali Wetland in the west and Gorgan Bay in the east), we searched for a possible matrilineal structure. The retrieved phylogeographic pattern was characterized by a shallow genealogy and lineage distributions varied, most probably caused by low to modest contemporary gene flow between populations of S. caspius across the southern Caspian Sea that are linked tightly through history.

“…Amongst the Caspian Sea wetlands is the Anzali Wetland Complex (AWC), which is located in the southern Caspian Sea (north Iran) and represents an important Ramsar biodiversity site (Esmaeili, Teimori, Owfi, Abbasi, & Coad, 2014; Jafari, 2009). More than 52 fish species inhabit the AWC (Abbasi et al., 2017) of which 15 are NN (Abbasi et al., 2017; Abdoli & Naderi, 2009), and of the 159 species comprising the Caspian Sea fish fauna (Naseka & Bogutskaya, 2009), 52 (33%) are found in the AWC.…”

Risk screening tools play a crucial role in identifying potential high‐risk non‐native (NN) fish species. In this study, potentially invasive NN fish species in the Anzali Wetland Complex (AWC), which is located on the south coast of the Caspian Sea (Iran), were identified using the Aquatic Species Invasiveness Screening Kit (AS‐ISK). Twenty‐nine freshwater fish species were screened of which 13 exist in the AWC and 16 in close proximity to it (“horizon” species). Receiver operating characteristic curve analysis showed that AS‐ISK could discriminate reliably between non‐invasive and invasive fish species for the AWC. Mean threshold scores were 3.25 for the Basic Risk Assessment (BRA) and 11.75 for the BRA + CCA (BRA + Climate Change Assessment), and these, respectively, classified 89.7% and 86.2% of the species as high risk. The CCA resulted in an increase in the BRA scores for 86.2% of the species, suggesting the need to account in future NN species management for a likely increased invasiveness of those species under future climate conditions. These results suggest that AS‐ISK could prove an effective tool for identifying potentially invasive NN freshwater fishes in other wetlands of the Caspian Sea basin.

“…The north Caspian Sea and associated drainage basin is the most important fishery of Kazakhstan, with about 0.3 million tons of fish caught annually. In total, 80 species or subspecies of fish are found in the northern part of the Caspian Sea (Naseka & Bogutskaya, 2009). These include freshwater species found close to the coast and rivers of the drainage basis, as well as marine species found in areas of higher salinity.…”

The northern section of the Caspian Sea and lower reaches of the Zhaiyk (Ural) River is an important fishery for Kazakhstan. In the present study, a total of 1597 individuals of ten fish species were analysed. The fish were caught over three years, from 2018 to 2020. For each species studied – Abramis brama, Alosa saposchnikowii, Atherina boyeri caspia, Carassius gibelio, Chelon auratus, Cyprinus carpio, Leuciscus aspius, Rutilus caspius, Sander marinus and Sander volgensis – between 100 and 200 individuals were examined. A series of generalized linear models (GLMs) were used to examine the association between individual parasite intensity of infection and the Fulton index, age, year the fish was captured, where the fish was captured (northern Caspian or Zhaiyk River) and sex. For each GLM, the best-fitting probability distribution was used –either Poisson, zero-inflated Poisson, negative binomial or zero-inflated negative binomial. For some fish/parasite species, an increased Fulton index was associated with higher intensities of parasite infection, whilst, for others, the Fulton index decreased with the intensity of parasite infection. This was also true of age-related intensity of infection, with some parasites having an increased intensity of infection with age whilst others had a decreased intensity of infection with age. There was also some evidence of variation in intensity of parasite infection between different years when the fish were caught. For some species of fish that are endemic to both the fresh waters of the Zhaiyk River and the low-saline waters of the northern Caspian, there were variations in intensity of parasite infection between the two environments. The best-fitting probability distribution also gave some information about the dynamics of infection. No fish species had a Poisson distribution of parasites, which is consistent with an entirely random infection process, with all fish being potentially exposed. For some parasites, the distribution was a zero-inflated Poisson, which is consistent with either the fish being exposed to parasite infection or not; and, if exposed, infection was a random process. Other parasites had a negative binomial distribution, consistent with the entire fish population being exposed, but the infection process was clumped or there were variations in the susceptibility of infection between fish. Finally, some of the parasites had a zero-inflated negative binomial distribution, which can be interpreted as part of the fish population not being exposed and the remainder of the population being exposed to a clumped or aggregated infection process and/or a variation in individual susceptibility to infection.
